Abstract
Surgical instrumentation and a method for cutting bones on one or both sides of a joint such as the knee joint to allow the application of a joint prosthesis. A rod is inserted into the medullary canal of the bone to be cut. The rod is secured within the medullary canal and a router guide is mounted on the rod for rotation thereabout while being restrained against movement axially of the rod. A router or side cutting drill is inserted through the router guide into contact with the rod and actuated to rotate about its own axis. The router guide and the router are then caused to rotate about the rod to thereby cut the bone to produce a substantially planar surface thereon suitable to bear against a joint prosthesis.
